SPECIFICATION forming part of Letters Patent No. 636,790, dated November 14, 1899. Application filed March 8, 1899. Serial No. 708,204. (No model.)

To all whom t may con/cern.-

Beit known that I, ALFONSO DERAY GATES, a citizen of the United States, residing at Oleveland, in the county'of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Rolls for'Mitering the Ends of Railroad-Rails; and I do declare that the followingis a full,- clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to rolls for mitering the ends of railroadfrails; and the invention consists in the construction of rolls adapted to produce rails with mitered extremities of a novel pattern substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical.crosssection of a set of rolls-embodying my invention and having the peculiarities of formation substantially as shown partly in this view and partly in other views and as hereinafter described. Fig. la. same sheet, is a cross-section of a portion of the rolls and the rail on line .fr x, Fig. 1, this being the starting -`point whence the rolling goes toward the extremity of the rail, the presumption being that the entire rail has been passed through suitable rolls preliminary to this particular set to fashion it to the shape seen in this cross-section. Fig. 2 is a vertical central cross-section of the rolls and having the rail between them advanced about half-way the length of its miter; and Fig. 2a is a cross-section onze, Fig. 2, in which the miter is shown the full width of the rail, the same as is seen in the rail itself midway in Fig. 13. Fig. 3 is a display viewof the working faces of the two aboveillustrated rolls, the same being laid ont upon a straight line and in this sense diagrammatic. Figs. 4 and 4, which are companion views, respectively, show cross-sections of the rolls on lines 4 4 and 4a 4a, Fig. 3. Figs. 5 and 5a show crosssections with the rolls advanced to a point corresponding to 5 and 5a, Fig. 3. Figs. 6 and 6a correspond to the section -lines on cross-lines 6 anda, Fig. 3. Figs. 7 and 7a correspond to cross-section lines 7 and 7 a, Fig. 3. Figs. 8 and 8? correspond to cross-section l tion.

lines 8 and 8a, Fig. 3; and Figs. 9 and 9 correspond to lines 9 and 9a on Fig. 3. Fig. 10, Sheet 4, is an edge elevation of an end section of my improved rail; and Fig. 11 is a plan view thereof. Fig. 12 is a side elevation of said rail-section broken and turned at the center to show a cross-section at that point, and Fig. 12L at its end is an end sec- Fig. 13 shows the reverse side to that seen in Fig. 12, and Fig. 13?L vis an end elevation looking along the line of the rail and showing the enlargements and deflections hereinafter described. Fig. 14 is a plan section looking down on a line corresponding to line a a, Fig. 13,A butwith two rails united.

The product of the rolls (shown fully in Sheet 4) isthe subject-matter of a concurrent application, led on the 8th day of March, 1899, Serial No. 708,203, and is brought into this case to assist in illustrating and understanding the construction ofthe rolls.

A and B represent `the two rolls, Figs. 1 and 2, and C is the rail. Before reaching these rolls the rail is supposed to have undergone such preliminary rolling as to bring it approximately to form in cross-section as seen in Fig. 1f. Having reached this point, the next step introduces myinvention, which is to reduce the extremities of the rail to the shape seen more particularly in Sheet 4 of the drawings, with a long miter-joint. To this end I employa set or sets of rolls having the changing formations shown in Figs. 4 to 9 and 4a to 9%, inclusive-that is, I may have one set for each and with an intermediate set to finish the rail from miter to miterin several passes, the ends being rolled alternately, or I may have one set adapted to take the rail through several passes to completion, first at one end and then at the other. Whatever way is found most convenient may be adopted. Hence, also,l a description of a single set of rolls is sufficient for all the purposes of this invention. y

Figs. 10 to 14 show just what are the peculiarities of formation of my new rail; First of all it has a diagonal vertical bevel 2, projecting from 23L to 2fL ou the head a and from 2b to 21 on the flange of the base and at the middie of its length a bevel the full depth of the rail, thus forming a broad fiat beveled or mi- IOO tered surface at said middle point. The entire length of this miter is straight both lengthwise and vertically, and at its forward part it projects across the tongue 3 and loses itself in the feathered extremity a2 of the head and in a like extremity 2b in the ange b. This miter-line runs across the axial line of the rail at a long inclination, so as to form only a gradual reduction in the strength and tread of the rail and so that the tread decreases in cross-section on one rail as it is increased in the other and all without any break in the joint, thus giving durability and strength to the jointand practicallycontinuous tread not otherwise possible.

In connection with the long straight initer 2 we have the deflection of the web c from its norma-l line centrally of the rail wholly to one side of said line, and the tongue 3, which is a practical extension of the web, projects from said deflection. This construction is plainly seen in Fig. Il, where the beginning of deflection from the inner side of the web is at the cross-line 5 and ends at cross-line 5b, which is also the beginning of the tongue proper. The said tongue becomes an overlapping portion for the connecting-rail, corresponding in all essentials to a fish-bar, but with the added advantage of being an integral part of the rail itself. The outer flange of the rail continues the full length of the tongue, Figs. l() and le, and the head d also extends its full length, but is reduced to something more than a bead ci', as seen in cross-section l2.

Three points of construction are developed in connection with the miter or bevel 2 and the deilection of the web and tongue. First of these is the gradual deepening laterally on its outer side of the web from a point back on the rail until it reaches cross-line 5, Fig. 14, which is about its deepest orlaterally-thickest point. Here also in a senso is the weakest point of the opposite rail C. From this point to 5b the web of rail C rapidly retreats laterally on its inner side wholly to the outside of its normal line, while the web on rail C retreats in like manner, but in the opposite direction to cross-line 5, and the two tongues 3 of the two rails project in opposite directions on opposite sides, one from line 5 and the other from line 51, and are bolted with several bolts each to the rail they overlap. The next of the said three points is the gradual deepening of head a down upon or over the web c, as seen in Fig. l2, and the third is the upward deepening of the corresponding flange Z9, as likewise seen in Fig. l2, both the said deepenings or enlargements increasing toward the extremity of the rail and together materially reducing the depth of the web, which itself has been deepened laterally, as above described. All these lilies of deepening in head, web, and flange are gradual and uniform, so as to make rolling practicable,

and are so related to the bevel or miter 2 that the stock displaced in the miter formation is carried into these several portions as it may be needed to give the rail the desired shape and strength, the tongue 3 of course being developed in the same operation and out of the same stock. In the production of rolls to meet the needs of a rail having these several novel features I have necessarily had to go outside of all beaten paths in rail manufacture and have accomplished what experts in this art have invariably told me was impossible-produced the long straight miter by means of suitably-formed rolls, and, in fact, have in the same rolls and at the same time also developed all the associated features pe culiar to the mitered end of my new rail. In this undertaking the chief diculty of course has been to produce rolls by which the straight mitered surface with a diminishing cross-sec tion and the necessarily associated and varying formations of the rail could be wrought out inthe same operation. This, however, has been successfully accomplished by the rolls herein shown and the construction of which may be at least partially interpreted from the rail itself, as seen in the several figures.

The radius within which the entire formation of t-he mitered ends of the rails occurs is seen in Figs. l, 2, and 3 between the lines di (L4-that is, the radius between .these points covers the length of the miter of the flange b, the longest portion of the miter. Lines b3 b show the radius for forming the miter on the head a and lines c3 c4 the radius to form the deflection of the web of the rail from 5 to 5b, Fig. 14, and between which the miter extends across the entire depth of the rail.

Now examining the construction of the rolls and rails in detail reference is had to Sheet 3 of the drawings. Here the peripheries of the two rolls A and B, especially between radial lines a3 a4, are laid out flat and straight for purposes of comparison. The cross-lines N N in all the views indicate the normal radius or circumference of the flanges of the rolls, and any divergence from this normal line to either side thereof in both rolls is seen in the cross-sections at the side of Fig. 3.

The first development of the miter is wholly in the flanges l), as they are the widest portion of the rail, and as one flange is gradually depressed the opposite flange is also gradually thickened, the stock from one flowing more or less into the other. This continues alone till the are b3 b4 is reached on the same side, mitering the rail-head, and the corresponding arc d d on the opposite roll affecting the web. In these several progressions from the normal we see in Figs. 5 and 5 the first pronounced development in the rail where the head d and the corresponding flange b, Fig. 5, have almost disappeared and the two rolls have the formation in section seen in said figures. Here the channels in roll A for the head a and flange b have almost disappeared IOO IIO

in depth; but in the opposite roll B both head and iiange have perceptibly deepened and the intervening rib h has been correspondingly reduced, Fig. 5a, thus affording room for surplus metal and thickening of the web along this side, as seen at cross-line 5 5, Fig. 14.

The next measurementis disclosed in Figs. 6 and 61 and on the corresponding lines, Fig. 3. Here the roll A has a plain surface b2 equal to the distance between c3 c4, Fig. 3, and shown at cross-line 5a 5b, Fig. 14. This iattening, as it were, of roll A is at the expense of the flanges, ribs, and channels in its surface, which are absorbed in the swell of the roll; but it also involves a deepening of the whole working face of this roll from its axis, corresponding to the swell from the normal radius line N. (Seen at the leftin Fig. 2.) The normal radius has also developed with a fiat surface c3 c4 entirely across the face of the roll and from this point on till the rolls pass out of action at n', Fig. 2, and Fig. 3 the normal radius is crossed by the roll into the abnornal at a depth in each successive step seen by line NN in the several successive figures from Fig. 6 up. Meantime parts of the roll B recede from the normal relatively, as seen from Fig. 6L up to Fig. 9a, and in Fig. 6a the entire formation of the rail is in roll B except the flat miter.

Incident to the increasing radial depth of roll A from a3 to c4, representing in a working roll a depth of about five inches, is the construction to provide for the total side deflection of the web c and the tongue 3. The complete deiiection of the web c occurs at the base of tongue 3, between cross-lines c3 c4, Figs. 1 and 2, as already described, and the tongue is fashioned by the channel h' next beyond the Hat space c3 in prolongation of the web.

In all the views from Figs. 4a to 7a the rib h on roll B which deiines the web and the tongue on one side appears in decreasing prominence, according to the degree of deflection in web and tongue, and in decreasing cross-section according to the gradually-decreasing depth of the web by reason of the deepening of head c and flange b over the same. The correspond ing rib h2 in roll A loses itself entirely at the fiat surface b2, and from that point on a channel or groove h' takes its place to form alone the deiiected tongue 3. The surface b2 therefore bridges the space between rib h2 and channel h', and the said surface b2 between line c3 c4 has the relatively abrupt declivity seenbest in its elfect upon the rail from 5a to 5b, Fig. 14.

'The full measure of swell of the rail A from the normal radius or circumference indicated by the circular line N is seen by the location of said line in Fig. 2, and the same construction of roll continues past line a3 to the point n', where it abruptly recedes to the normal again. This continued space from a4 to n enables any surplus metal beyond what the tongue 3 requires to be worked out into an mal radius corresponding to the swell from c4 to n in the upper roll, so as to work harmoniously therewith.

I have herein purposely described the miter as straight, which it is shown to be and is the preferable construction; but a substantially similar formation is understood to be comprised in the language used and to be ernbraced in a construction involving the principle of my invention.

What I claim is- 1. The two rolls substantially as described, one of said rolls constructed to produce a longitudinally-inclined miter on the end of a rail and the other to thicken the web of the rail and at the same time deepen the head and the iian ge of the rail over the thickened side of the web and both of said rolls formed to produce a tongue on the end of the rail extending beyoud its mitered portions and having a flange at its bottom and a head at its top and located wholly outside the normal vertical plane of the web, substantially as described.

2. A set of rolls for forming miter-jointed rails, one of said rolls having a ribon its periphery gradually diminishing in depth and gradually narrowing toward its vanishingpoint, and having a plain space across its peri phery next to the said vanishing-point and a gradually-deepening groove next to said even space, said roll formed with a-swell in the portion embracing said groove, substantially as described.

3. In a set of rolls for forming a miter on and deflecting the end of a rail to one side of the median line of the rail, one of said rolls constructed to produce the miter and the two rolls to throw the web of the rail beyond the miter parallel to but bodily at one side of the web behind the miter, substantially as described.

et. In rolls for mitering and deflecting the ends of rails, a roll having a gradually-dminishing rib on its periphery and a plain surface extending across the face of the roll at the vanishing-point of said rib and a portion of the roll next beyond said plain surface extending outward beyond the normal radius of the roll and having a gradually-deepening groove, in combination with a companion roll having a gradually diminishing and retiring rib opposite the said rib and groove respectively in the first-named roll, substantially as described.
